DOOR-MOUNTING srmio'ronn.

Application filed May it"),v 1925. Serial No. 31,557.

. of angle or channel shape whichis built into the masonry of the wall. It frequently happens that after the metal partsare mounted in the wall the door frame'formed thereby is not exactly true and it is a very difficult task to properly and accurately mount the doors for successful and permanent operation.

It is an object of this invention, therefore, to provide a door mounting which will have flexibility to accommodate discrepancies in the building construction and in placing of the door frame members. I

It is a further object of the invention to provide a mounting in which the doors can be hung in true and accurate position and maintained in such position for continuous operation.

It is more specifically an object oftheinvention to provide adjustable track supporting brackets on the door frame and to provide laterally adjustable out-board pintles on which the door hinges swing, as well as a novel track and door hanger.

It is also generally an object to provide door mounting of simple and exceedingly rigid and stable construction.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the different views, and in which Fig. 1 is a View in front elevation of the assembled door mounting, the door being partially indicated therein; Fig. 2 is a view in plan of the door mountmg; a

Fig. 7 is a view in front elevation of a bracket used; and

Fig. 8 is a view in plan of a floor plate used.

Referring to the drawings a door frame is shown which comprises spaced members 1 of angular formation composed either of standard channels, as shown, or of single gles or double connected angles. A top cross member 2 connects the side members 1 and is connected thereto by angle members 3 to which both the top and side members are riv eted. The side members 1 each have apertion at projecting upwardly above the top member 2, the top member being cut away to accommodate this projecting portion, as clearly shown at the right of Fig. 2. 1 The members 1 and 2 are adapted to be set into the wall or the masonry of the building and to be firmly bondedtherein. A strip 6 formed of a rectangular bar extends across beneath the top member 2 and along the inside of the verticalmembers 1 and is spaced from the front edges thereof a distance substantially equal to the width of the door for which saidstrip forms a sill or stop.

-Tho doors are indicated at 7 and are supported partly from tracks 8,which latter are,

in turn, supported in members 9. These members 9 are adjustably supported longitudinally by side brackets 10. The side brackets 10 are clearly shown inFigs. 1 and 3 and comprise an attaching flange having vertical slots 12 adjacent its top and bottom portions adapted to receive attaching bolts which will 1 be screwed into the side members 1. It will be noted that each of said brackets is thus adjustably supported and the lower edge of this bracket, as clearly shown in Fig.1, extends below the top cross member 2. The bracket is provided with a channel-like portion at its forwardly projecting end in which the end portion of member 9 is disposed, said'latter member being provided with slots through which pass clamping bolts passing through holes in said brackets, to secure said member,

13 of which has rounded ends adapted to be received in and support the other ends of the tracks 8. The doors 7 have brackets 15 secured thereto in which screws 16 are threaded.

The screws 16 are adjustably held in the bracket 15 by nutsplaced thereon and clamped against both sides of said brackets. The said screws are also bored to receive the shanks of forked members 14, the enlar ed forked portion of the upper end of sai shank resting on the top of screw 16. The fork members 14 have set screws extending therethrough from opposite sides and pivotally supporting sleeves 17 which sleeves ride upon the tubular tracks 8. The tracks 8 are prevented from longitudinal movement by set screws extending through the members 9 and contacting therewith and compartively light coiled compression springs 8 are disposed on said tracks 8 adjacent the members 9. From the described structure it will be seen that both ends of t1acks'8 are capable of independent vertical adjustment, as are also the doors 7.

The doors 7 are arranged to be operated by a horizontal moving member moving in a line substantially perpendicular to the front of the frame and a motor sup rting frame 18 is provided secured in place y vertical members (not shown) depending from the ceiling, and also supported by horizontally extended members 19, the converging inner ends of which are bolted to plates which are, in turn bolted to inwardly projecting flanges at the top of brackets 10.

The doors are adapted to swing on hinges 20 which are of heavy strap formation and are spaced vertically at the outer side of the door. The tops of these'hinges swing on vertical pintles 21 disposed outwardly of the side members 1. Auxiliary vertical members 22 are provided which are rigidly secured in the wall, which members, as shown, extend upwardly to a short distance below the top of the members 1. Plates 23 are riveted to and rigidl tie the members 21 and 22 together, and p ates 24 provided intermediate their ends with pintle receiving'lugs are secured to the plates 23. The plates 24 have transversely extending slots therein adapted to receive the attaching bolts. With this structure, it will readily be seen that the plates 24 can be held in various positions transversely of the members 1. The upper plate 24 is not made adjustable but is bolted rigidly to its plate 23. The pintle members 21 are rigidly held in the lugs and plates 24 by set screws 26. Suitable bearing collars or washers 27 are disposed between the bot-" tom of the hinges 20 and the pintle receivlng lugs. As shown in Figs. 2 and 6, the hinge members 20 are provided with an offset adjacent the side members 1 so that the outer portions of the hinges are spaced from the front of said side members. This is an important feature in the construction to insure that the doors will be moved to closed posi- .tion without any binding at the corners of the frame.

The doors 7 are illustrated as each comprisin two hinged sections and these doors are fo ded outwardly at their-central portions and thus swing to open and folded positions, the operating mechanism being attached thereto, as shown in the patent above referred to. The hin es 20 are rigidly secured by bolts, or otherwise, to the outer sections and hinges 25 are bolted to the door sections at the other side thereof and hingedly connect said sections. A side of the hinge 25 on the outer door section is connected in rigid relation to the hinge 20 by bolts extending through both hinges, as shown in Fig. 6. With this construction and with the fixed upper plate 24, the axes of both hinges 20 and 25 are located in fixed relation to the sides of the door frame. A door plate 28 is used and set into the floor at the center of the frame. This plate is shown in detail in Fig. 8 and comprises vertically disposed oppositelly curved flanges between which the edges of t e doors pass and are guided into and held in closed position.

In settin the frame members 1, 2 and 22, into the wa l or masonry of the building, it usually happens that the frame is not true or square when the time comes for hanging the doors. It is vital and essential that the doors must hang accurately and true to avoid strains on the operating mechanism and the supporting members of the door. With the described structure, the doors can be mount ed to hang in true and accurate osition, regardless of discrepancies in the ramc. The brackets 10 and 11 can be vertically adjusted to bring the track and the operating frame members 19 into correct position, and the tracks 8 can be adjusted by the members 9 and the door by means of screws 16 carefully adjusted to the, tracks. The pintle 21, by lateral adjustment of the lower lates 24, can be brought to accurate vertica position and rigidly secured in such position. This pintle can 'also be adjusted forwardly and rearwardly by shims 24 placed under the plates 24 and bolted thereto by the attaching olts for the plates 24. As stated, the pintles 21 are located-a definite distance outward from the upper portion of the side members 1 of the door frame and these pintles will, as stated. he plumbed or brought to accurate vertical position by adjustment of the lower plates 24. The distance of the upper end of the pintle from the door frame can thus be determined for all installations and the distance between the axis of the pintle and the axis of the hinge for the door sections will also be determined. The doors will thus hang in accurate vertical position even through the frame is slightly out of true. The outer edges of thedoor sections will, of course, be finished to correspond to the door are swung to open position by the operator, they fold upon each other and the sleeves 17 A frame and fit snugly against the strip 6.

As thegdoors and the various parts of the I mounting, as Well as the frame members 1 and 2 are made at the factory, it is essential that the parts be so constructed that they can be shipped ,to the building for installation and be erected with a minimum of labor in.

accuratelymounted position. As the doors slidealong" the tracks 8 and the doors compress the springs 8 as they come to open position. The motor is such that the doors are brought to folded posit-ion on one stroke and then later moved to closed position by the re- .turn stroke of a cylinder plunger.

The

springsB thus act to cushion the doors as they come to rest'in the open position and also tendsto assist in the starting movement of the doors as they are started toclosed position.

-1 The door thus being accurately mountch'the operating mechanlsm being carefully brought so strong and rigid that'there'is no chance for the operating jars todislocate or-disarrange the parts thereof. Numerous'installa tions ofthe doors and frame have been made "and have operatedfor months without one pai ticle'of attention for maintenance or re pair. "The utility and efficiency of the invention have therefore been amply demonstrated inactual practice and the said inv'cn tion constitutes a great advance/in the art" and is receiving widespread attention.
